Description

  TECHNICAL FIELD The present invention relates to a driving device that drives an aviation obstacle light that is provided in a building, a structure, or the like and indicates its presence to an aircraft, and an aviation obstacle light that includes the driving device. The present invention relates to an aircraft obstacle light equipped with a device.

  Conventional aviation obstruction lights are provided in buildings such as high-rise buildings, structures such as radio towers and chimneys, etc., and are intended to prevent aviation accidents by showing their presence to the aircraft in flight. The effective luminosity, the number of flashes, the direction in which the lamp can be visually recognized, etc., are stipulated in the Aviation Law Enforcement Regulations.

  Conventionally, some aviation obstruction lights, such as medium-luminance aviation obstruction lights and high-luminance aviation obstruction lights, have the number of flashes per minute specified by the enforcement regulations of the Aviation Law. This blinking has been performed by turning on and off a voltage of 100 V on the power line. Further, for example, there is one disclosed in Patent Document 1 as an aviation obstacle light that changes the voltage to blink the light source. That is, the voltage of the commercial power supply is kept as it is during the lighting time of the halogen light bulb of the light source, and only the voltage of the phase of 150 ° to 180 ° and 330 ° to 360 ° in the voltage of the commercial power supply is set during the extinguishing time. Is.

  However, aviation obstacle lights that use light bulbs as light sources have various improvements such as high power consumption, large shape, and large mass. In addition, a light bulb that has been able to emit light but cannot maintain a predetermined effective luminous intensity must be replaced. For this reason, there is a problem that the light bulb needs to be replaced after being used for about 1500 hours, and the replacement work must be frequently performed.

  Thus, in order to solve these improvements and problems, it is conceivable to use a light emitting diode (LED) as the light source. However, in the case of a light bulb, power is supplied by an AC power source, but in the case of an LED, it is necessary to use a DC power source. For this reason, when changing from a conventional aviation obstacle light using a light bulb to an aviation obstacle light using an LED, if the existing power supply line is used as it is, the equipment investment can be reduced. In this case, a capacitor is used to full-wave rectify the AC voltage and smooth the full-wave rectified voltage.

  In order to increase the smoothness of the smoothing voltage, a capacitor having a large capacity is used. For this reason, the rise when the power supply line is turned on becomes dull. On the other hand, the medium-light aviation obstacle light, for example, needs to blink a plurality of medium-light aviation obstacle lights arranged in a building in synchronization with each other. Therefore, if the rise of the voltage waveform when the power supply line is turned on is slow, it becomes impossible to synchronize the medium-light aviation obstacle lights, and the requirements stipulated in the Aviation Law Enforcement Regulations cannot be satisfied.

  The present invention has been made paying attention to such problems of the conventional technology, and includes a driving device for an aviation obstacle light that can be synchronized using a conventional power source light and the driving device. The purpose is to provide aviation obstruction lights.

The gist of the present invention for achieving the above object lies in the inventions of the following items.

The power factor correction drive unit (57) monitors the input voltage waveform and suppresses an inrush current to the capacitor (56) connected between the rectifier circuit (54) and the power factor correction drive unit (57). .

  Further, in the power factor improvement drive section (57), the power factor is improved, the constant current flowing through the light emitting element (11) is switched, and the smoothing circuit (58, 59) is smoothed to supply the constant current to the light emitting element (11). Adjusted to flow. Since the capacitor (56) has a predetermined small capacity, the aviation obstacle light (1) can be blinked with a predetermined response.

  According to the aviation obstruction light (1) described in the item [2], since the blinking operation can be performed with a predetermined response to the on / off of the AC power supply line, a plurality of power supplied from the same AC power supply line can be used. The aviation obstacle light (1) can be blinked in synchronization by turning on / off the AC power line.

  According to the drive device according to the present invention, since the conventional power source lie can be used, the introduction cost of the aviation obstacle light using the LED as a light source and provided with the drive device according to the present invention can be suppressed. In addition, since the drive device according to the present invention exhibits a predetermined response by reducing the capacitance of the input side capacitor, the Aviation Law is enforced between a plurality of aviation obstacle lights equipped with this drive device. Synchronous light emission that satisfies the rules can be performed.

Hereinafter, a preferred embodiment of the present invention will be described with reference to the drawings.
Each figure shows an embodiment of the present invention.
FIG. 1 shows a configuration of a medium-light aviation obstacle light 1 including a driving device 50 according to the present embodiment.
The medium-light aviation obstacle light 1 is provided in a building such as a high-rise building, a radio tower, a structure such as a suspension bridge, and the like to indicate its existence to an aircraft, thereby preventing an aviation accident.

  In the medium-light aviation obstacle light 1, a mounting plate P is fixed on the opening edge of the base B so as to cover the opening. On the mounting plate P of the base B, four LED substrates 10 on which a plurality of LEDs (Light Emitting Diodes) 11 as light emitting elements are mounted as light sources are provided.

  The LED 11 is lit and blinked via the driving device 50 shown in FIG. As shown in FIGS. 1 and 10, the driving device 50 is mounted on the power supply substrate 41 accommodated in the accommodation case C. The storage case C is formed in a pan shape, and the inside is an internal space 40. The internal space 40 accommodates a power supply board 41, a noise filter 42, a terminal block 43 for connection to an external power supply, a surge absorber 44 connected to the terminal block 43, and the like.

  FIG. 3 is a block diagram showing the driving device 50 and the LED substrate 10. In FIG. 3, “lower lamp body side” indicates the inside of the housing case C of the medium-luminance aviation obstacle light 1, and “upper lamp body side” indicates the upper side of the housing case C.

  The terminal block 43 is connected to an external 100V AC power supply line. A surge absorber 44 is connected between the terminal block 43 and the noise filter 42 as a countermeasure against induced lightning. The noise filter 42 suppresses noise entering from the outside over a wide frequency band.

  What attached | subjected the code | symbol 50 with which the noise filter 42 is connected is an LED drive circuit, and is the drive device 50 which concerns on this Embodiment. Each LED 11 mounted on each of the four LED boards 10 blinks by the output from the driving device 50.

  FIG. 2 is a block diagram showing the driving device 50 according to the present embodiment. The input side connector 51a is connected to the noise filter 42 shown in FIG. A protective circuit 52a is connected to the input side connector 51a. The protection circuit 52a uses a fuse to prevent an overcurrent flow. A noise filter 53 is connected to the protection circuit 52a. The noise filter 53 reduces noise generated by switching in the power factor correction drive unit 57 composed of a dedicated IC described later.

  A rectifier circuit 54 is connected to the noise filter 53. The rectification circuit 54 performs full-wave rectification of the alternating current. An input side capacitor 56 is connected in series between the output side of the rectifier circuit 54 and the 0V line of the driving device. The input side capacitor 56 can improve the response of the blinking operation of the LED 11 as the capacitance is reduced. Therefore, the input side capacitor 56 is small so that it can be synchronized with the blinking operation of the medium-light aeronautical obstacle lights 1 provided with a plurality. Thereby, a power factor also improves.

  The power factor correction drive unit 57 supplies or stops a constant current to the LED 11 according to the on / off operation of the power supply line. The power factor correction drive unit 57 is composed of a dedicated IC.

  A protection circuit 52 b is connected to the output side of the power factor correction drive unit 57. This protection circuit 52b prevents the occurrence of overvoltage when the LED 11 fails in the open mode.

  A coil 58 is connected between the output side of the power factor correction drive unit 57 and the input side of the protection circuit 52b, and output between the coil 58 and the input side of the protection circuit 52b to the ground line. A side capacitor 59 is connected to form a smoothing circuit.

  Another protection circuit 52c is connected to the output side of the protection circuit 52b. The protection circuit 52c includes a thermal fuse, and shuts off the output when an abnormal temperature occurs. The output side of the protection circuit 52c is connected to the output side connector 51b. The LED 11 is connected to the output connector 51b as shown in FIG.

  A heat radiation sheet (not shown) is interposed between the LED substrate 10 on which the LEDs 11 are mounted and the mounting plate P. The mounting plate P has a plurality of penetrating air holes p1 formed around the LED substrate 10. This air hole p1 is for accelerating convection of air in the medium-light aviation obstruction light 1 due to heat generated by the light source.

  As shown also in FIG. 4, the mounting plate P detachably fixed to the base B is attached with a reflecting member 20 having a shape that opens and extends in a direction away from the LED 11 in the optical axis direction of the LED 11. Yes. The center of the reflecting member 20 and the center of the mounting plate P coincide with each other.

  The mounting plate P attached to the base B, the LED substrate 10 attached to the placement plate P, the LED 11 attached to the LED substrate 10, and the reflecting member 20 attached to the placement plate P It is one unit. For this reason, they can be attached to and detached from the base B together when the light source is replaced or maintained. The base 30 has a glove 30 that is accommodated so as to cover the entire unit. For example, it is bonded by a hot melt adhesive.

  FIG. 9 shows the overall appearance of the medium-light aviation obstacle light 1 with the globe 30 fixed to the base B. The globe 30 is entirely made of a transparent material and is formed in a dome shape having a top portion. The ceiling portion of the globe 30 suddenly decreases in diameter from the vicinity immediately above the periphery of the large-diameter opening of both openings of the reflecting member 20 and reaches the top. A diffusion portion 31 that increases light diffusion is formed at the top portion and the peripheral portion thereof. The diffusion portion 31 is formed by forming a concentric smooth waveform on the inner surface side of the globe 30. The material of the globe 30 is, for example, an acrylic resin.

  FIG. 5 is a longitudinal sectional view showing a longitudinal section of the reflecting member 20. The reflecting member 20 is formed of resin and is formed in a trumpet shape or a funnel shape having openings at both ends. The outer surface 20a of the reflecting member 20 is plated in order to reflect light from the LED 11. Further, the reflecting member 20 is provided with a plurality of penetrating light emitting holes 21. The light emitting holes 21 are arranged at equal intervals on the same circumference.

  Although the center of the reflecting member 20 and the center of the mounting plate P coincide with each other as described above, an opening having the same diameter is formed at the center and its peripheral part. The inside of the reflecting member 20 and the base B communicate with each other through the through hole p2 of the mounting plate P. A through hole b1 having a diameter smaller than that of the through hole p2 is formed at the bottom of the base B immediately below the through hole p2. For this reason, there is no mounting plate P in the part which faces the inner surface of the reflection member 20, Therefore, LED11 is not arrange | positioned in the position which faces the inner surface of the reflection member 20. A modified example in which the LED 11 is also disposed at a position facing the inner surface of the reflecting member 20 will be described later.

  The overall shape of the reflecting member 20 and the number and arrangement of the light emitting holes 21 are such that the light reflected from the outer surface 20a and the light that has passed through the light emitting holes 21 are stipulated in Article 127 of the Air Law Enforcement Regulations. It is formed to diffuse to fill. In other words, the medium-intensity white aviation obstacle light is formed so that the lamp light can be visually recognized from all directions above 5 degrees below the horizontal plane including the center of the light source. Further, in the medium-intensity red aviation obstacle light, the lamp light is blinking in aviation red so that it can be seen from all directions above 15 degrees below the horizontal plane including the center of the light source.

  FIG. 6 is a plan view of the medium-light aviation obstacle light 1 with the globe 30 removed from the base B. FIG. The plurality of LEDs 11 are disposed below the outer surface 20 a of the reflecting member 20. The four LED substrates 10 on which the plurality of LEDs 11 are mounted are formed in a shape obtained by dividing a belt-like ring into four. In the illustrated example, the LEDs 11 are arranged on the same circumference so as to be arranged at equal intervals. The optical axis of each LED 11 faces the outer surface 20 a of the reflecting member 20. In addition, since it will become complicated if code | symbol "11" is attached | subjected to all LED11 in FIG. 6, the code | symbol of LED11 is abbreviate | omitted suitably. In addition, although the LED board 10 which mounts LED11 shall be formed in the shape which divided | segmented the strip | belt-shaped annular ring into 4 parts, it may be the thing of the shape divided | segmented not only into 4 divisions but to several other sheets. Furthermore, the LED substrate 10 is not limited to a shape obtained by dividing a belt-like ring.

  Further, the plurality of light emitting holes 21 allow a part of the light emitted from the LED 11 to pass through as it is. The inner surface of each light emitting hole 21 is subjected to a mirror surface treatment that is plated like the outer surface 20 a of the reflecting member 20. Thereby, the light traveling from the LED 11 toward the inner surface of the light emitting hole 21 is absorbed by the inner surface and is not attenuated, but is reflected on the inner surface and then passes through the light emitting hole 21. The light emitting hole 21 also serves as a flow path through which air convected by the heat generated by the light source flows between the space where the LED 11 is disposed and the space on the opposite side of the reflecting member 20.

  In FIG. 7, among the light emitted by the plurality of LEDs 11, the light path L <b> 1 of the light reflected on the outer surface 20 a of the reflecting member 20, the light path L <b> 2 of the light passing directly through the light emitting hole 21, and the light reflected on the inner surface of the light emitting hole 21 Then, an optical path L3 of light that passes through the light emitting hole 21, and an optical path L4 of light that does not pass through the light emitting hole 21 and does not reflect on the outer surface 20a are shown. Further, FIG. 8 shows a state of air convection due to heat inside the medium-light aviation obstacle light 1. As shown in the figure, the convection of the air passes through the light emitting hole 21, the air hole p1, the through hole p2, etc., and the entire interior of the medium-light aviation obstacle light 1, and it can be seen that heat can be diffused satisfactorily.

  As shown in FIGS. 1 and 9, the glove 30 bonded to the base B with a hot melt adhesive is detachably fixed to the housing case C with screws at the outer edge portion rather than the bonded portion. A packing 101 is interposed between the fixing portion by the screw and the bonding portion. Thereby, the medium intensity aviation obstacle light 1 has waterproof performance.

  The storage case C is formed in a pan shape, and the inside is an internal space 40. As shown in FIG. 10, the internal space 40 accommodates a power supply board 41, a noise filter 42, a terminal block 43 for connection to an external power supply, a surge absorber 44 connected to the terminal block 43, and the like. ing.

Next, the operation of the driving device 50 for the aircraft obstacle light 1 according to the present embodiment will be described.
The AC power line to be turned on / off is connected to a terminal block 43 provided in the aviation obstacle light 1 and supplies AC power. The alternating current supplied to the terminal block 43 is input via the input side connector 51 a of the driving device 50 after the noise is suppressed by the noise filter 42. Thereafter, the signal is input from the protection circuit 52 a to the rectifier circuit 54 through the noise filter 53.

  The protection circuit 52a prevents the input of an overcurrent by blowing a fuse when an overcurrent occurs. Further, the noise filter 53 reduces noise generated due to switching of the power factor correction drive unit 57.

  In the rectifier circuit 54, the input alternating current is full-wave rectified and input to the power factor correction drive unit 57. The power factor correction drive unit 57 monitors the input voltage waveform and suppresses the input of the inrush current to the input side capacitor 56. Further, the power factor improvement drive unit 57 improves the power factor and smoothes it by a smoothing circuit including the coil 58 and the output side capacitor 59. Since the input side capacitor 56 has a small capacity so that the responsiveness of blinking of the LED 11 satisfies a predetermined condition, the aviation obstacle light 1 can exhibit excellent responsiveness.

Next, an operation of the aviation obstacle light 1 provided with the driving device 50 of the present embodiment will be described.
The aviation obstruction light 1 provided with the drive device 50 performs a blinking operation while exhibiting excellent responsiveness to on / off of the AC power supply line. Therefore, a plurality of aircraft obstacle lights 1 fed by the same power supply line can be blinked with high synchronization by turning on / off the power supply line.

  As shown in FIG. 7, according to the medium-light aeronautical obstruction light 1 of the present embodiment, the LED 11 disposed below the outer surface 20 a of the reflecting member 20 includes the power supply housed in the housing case C. Power is supplied from the substrate 41 and the like, and light is emitted while being controlled.

  The light emitted by the LED 11 is reflected by the outer surface 20a of the reflecting member 20 and then passes through the globe 30 and is emitted to the outside of the medium-light aviation obstacle light 1 and through the light emitting hole 21 of the reflecting member 20. From the LED 30 to the outside of the medium-light aviation obstacle light 1 and from the LED 11 to the globe 30 by being irradiated at an angle smaller than the angle hitting the reflecting member 20 and passing through the globe 30. It is divided into those that shine outside the medium-light aeronautical obstacle light 1.

  The light emitted from the medium intensity aviation obstacle light 1 is emitted so as to satisfy the requirements stipulated in Article 127 of the Aviation Law Enforcement Regulations. Thus, even if it is a medium-light aviation obstruction light, the LED 11 that is a light source is only required to be disposed on a single plane on the LED substrate 10 provided on the base B, so that the height can be reduced. In addition, the number of parts can be reduced and the weight can be reduced.

  When the medium-light aviation obstacle light 1 is turned on, the light source generates heat. As a result, air convection occurs inside the medium-luminance aviation obstruction light 1. At this time, the medium-luminance aviation obstruction light 1 has a plurality of light holes 21 formed in the reflecting member 20 so that spaces on both sides of the reflecting member 20 communicate with each other. The space on both sides of the mounting plate P communicates with the air hole p1 and the through hole p2 opened in the center.

  Further, since the space between the base B and the mounting plate P and the internal space 40 of the housing case C communicate with each other through the through hole b1 formed in the center of the base B, the medium-luminance aviation obstacle light 1 Air convection occurs throughout the interior. As a result, the heat generated by the light source diffuses widely inside the medium-light aviation obstacle light 1 so that the heat does not reach a specific part, and the heat radiation from the medium-light aviation obstacle light 1 is improved.

  When maintaining the effective light intensity of the medium-light aeronautical obstacle light 1 at a specified value or replacing the LED 11 for maintenance, the glove 30 is removed from the housing case C by removing the screw. Next, remove the wiring connected to the power supply side. Thereafter, the base B bonded to the globe 30 may be peeled off from the globe 30 and replaced with another unit. Therefore, maintenance of the medium-light aviation obstacle light 1 can be easily performed. Moreover, since the light source is the LED 11, the interval between light source replacements becomes long.

  11 and 12 show modified examples in which the light source of the medium-light aviation obstacle light 1 is different. The difference between this modified example and the above-described embodiment is that the LED 11 is arranged at a position facing the inner surface of the reflecting member 20.

  In the illustrated example, the LED substrate 10 a is disposed in the center opening of the reflecting member 20. This LED substrate 10a has a shape obtained by dividing a belt-like annular ring along the opening at the center of the reflecting member 20 into two parts. Two LEDs 11 are mounted on each of the two LED substrates 10a. That is, the four LEDs 11 are disposed at positions facing the inner surface of the reflecting member 20. These four LEDs 11 are arranged at equal intervals on the same circumference. In addition, although LED board 10a which mounts LED11 shall be formed in the shape which divided | segmented the strip | belt-shaped annular ring into 2 parts, it may be the thing of the shape divided | segmented not only into 2 parts but into several other sheets. Furthermore, the LED substrate 10a is not limited to a shape obtained by dividing a belt-like ring as long as the LED substrate 10a has a shape that does not block the through hole p2 of the mounting plate P.

  Since the four LEDs 11 are arranged in this manner, the center of the reflecting member 20 and the center of the mounting plate P are the same as the above example, but the opening diameter of the center of the reflecting member 20 is the same. Is larger than the opening diameter at the center of the mounting plate P, and the inner diameter formed by the two LED substrates 10a disposed along the opening of the reflecting member 20 and the opening diameter at the center of the mounting plate P are approximately. It is formed in the same size.

  In this modification, in addition to the light that has passed through the light emitting hole 21, light is emitted directly from the four LEDs 11 toward the top of the globe 30 and its peripheral part. Thereby, the light quantity in this direction can be increased. It should be noted that the arrangement of four LEDs 11 is merely an example, and may be three or two.

  According to the aviation obstacle light driving apparatus 50 according to the present embodiment as described above, the medium-light aviation obstacle light 1 including the driving apparatus 50 can be installed using a conventional power line. Moreover, it can be made to emit light in a desired synchronization between the plurality of medium-light aviation obstacle lights 1. Further, according to the medium-light aviation obstruction light 1, the power consumption can be reduced to about 30 W compared to the conventional medium-light aviation obstruction light using two 500W light bulbs. In the modification, when the two LEDs 11 are disposed at a position facing the inner surface of the reflecting member 20, the power consumption can be reduced to about 35W. Further, the mass can be reduced to about 1/4 from about 40 kg to about 10 kg. Thereby, installation workability | operativity can be improved. Furthermore, the time until the light source is replaced is increased from about 1,500 hours to 30,000 hours, and the number of replacement operations can be greatly reduced.

  In the present embodiment, the LEDs 11 are arranged at equal intervals on the same circumference. However, the light emitted from the medium-light aviation obstacle light 1 is defined in Article 127 of the Air Law Enforcement Regulations. As long as a certain requirement is satisfied, it may be arranged on two or more circles, or may not be arranged on a specific circle as long as it can emit light evenly as a light source.

Similarly, the light emitting holes 21 may be arranged on two or more circles as long as the light emitted from the medium-light aviation obstacle light 1 satisfies the requirements stipulated in Article 127 of the Aviation Law Enforcement Regulations. However, if the arrangement is such that the light that has passed through the light emitting holes 21 is uniform, it is not necessary to make holes so as to align them on a specific circumference.
Moreover, although the reflecting member 20 was demonstrated as what plated resin-molded thing, it may be functionally metal. However, when it is made of metal, it is inferior to that of resin in terms of weight reduction of the medium-light aviation obstacle light 1.

  The present invention is a drive device provided for a medium-light aviation obstacle light, but can be widely applied to a lamp using an LED as a light source.
